The fel pro gasket set and head bolts + head bolt tool will be close to 300 and then you'll need RTV sealant. Another probably 200 for the Aisin water pump.

During COVID, that water pump was on backorder from Ford so I used one from Gates. I guess Gates had a bad batch and 2 of their's failed in the span of less than a year.

Cons: bad batch, failed quickly

The Aisin kits are fine. I would not use a gates kit; the water pumps are junk and so are the tensioners

Pros: Aisin kits are fine

Cons: water pumps are junk
